Is there an intention to support other calendars e.g. Outlook,MobileMe, Yahoo Calendar, MS Exchange etc. in the Ajax Event Calendar?

Answer:

Actually you can see the Google Calendar as primary source. You can bind other Calendars, import or sync Outlook Calendars, sync also MobileMe - all to the Google Calendar.

Then you can use that Google Calendar as source for your Ajax Event Calendar. the Ajax Event Calendar binds live to a Google calendar so as soon as an appointment comes in the Google Calendar it is also shown in the Ajax Event Calendar.

Outlook and MS Exchange -> Google Calendar

You can use the Google Calendar Sync tool to synchronize automatically your Outlook or MS Exchange calendar with Google calendar
